The iPhone 11 does not have a 5G (NR) capable modem. The 3.5Ghz freq support is for the CBRS bands in the US. Support for 5G is not just a freq band support, it requires a chipset/modem capable of support the NR protocol.

(makes think of 4G+ which is already widely available since some months).This is an important point.iphone 11 is sold since September, with a feature list including codecs and frequencies which make think of 5G.The iPhone certainly doesn't support 5G, but it does support 802.11ax.This is the list of features:Cellular and Wireless Model A2111* FDD‑LTE (Bands 1, 2, 3, 4, 5, 7, 8, 12, 13, 14, 17, 18, 19, 20, 25,26, 29, 30, 66, 71)TD‑LTE (Bands 34, 38, 39, 40, 41, 42, 46, 48) CDMA EV‑DO Rev. A (800, 1900 MHz) UMTS/HSPA+/DC‑HSDPA (850, 900, 1700/2100, 1900, 2100 MHz) GSM/EDGE (850, 900, 1800, 1900 MHz) All models Gigabit-class LTE with 2x2 MIMO and LAA4 802.11ax Wi‑Fi 6 with 2x2 MIMO Bluetooth 5.0 wireless technology Ultra Wideband chip for spatial awareness5 NFC with reader mode Express Cards with power reserveThe list of bands seems long, much longer than what my eye is used to. It is an expression of new chips extremely parametrable and generic. The band 71 seems to have inside some specifics to 5G, somewhere in the UHF (hundreds of megahertz). The bands 42 and 48 are in the 3.5GHz area. The 3.5GHz are is where it is likely that some bands are to be allocated for 5G in France. (other likely 5G frequencies are in the UHF, in 20-something GHz, 60-something and 70-something). It is for these reasons I believe iphone 11 is ready for 5G. AlexMark.
